Targeted radiofrequency ablation (also written t-RFA) is a minimally invasive procedure to treat severe pain and discomfort caused from metastatic tumors in the vertebral body of the spine. This procedure uses radiofrequency energy to target and ablate a specific spinal tumor, causing it shrink and reduce the pressure on the surrounding nerves ...
Radiofrequency waves are used to produce heat on specifically identified nerves surrounding the facet joints called the lumbar medial branches of the dorsal ramus of the spinal nerves. [33] By generating heat around the nerve, the nerve is ablated, thus destroying its ability to transmit signals to the brain.
In the lumbar spine, facets provide about 20 percent of the twisting stability in the low back. Each facet joint is positioned at each level of the spine to provide the needed support especially with rotation. [citation needed] Facet joints also prevent each vertebra from slipping over the one below.
Magnetic resonance image of lumbar spine Nerve block of the cervical spine. Lumbar sympathetic neurolysis is typically used on patients with ischemic rest pain, generally associated with nonreconstructable arterial occlusive disease. Although the disease is the basis for this type of neurolysis, other diseases such as peripheral neuralgia or ...
Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. Local anesthetic nerve block (sometimes referred to as simply "nerve block") is a short-term block, usually lasting hours or days, involving the injection of an anesthetic, a corticosteroid, and other agents onto or near a nerve.
Superior cluneal nerve dysfunction is a clinical diagnosis that can be supported by diagnostic nerve blocks. [1] The superior cluneal nerves were first described by Maigne et al. in 1989 as a source of low back pain. [2]
The third lumbar spinal nerve (L3) [3] originates from the spinal column from below the lumbar vertebra 3 (L3). L3 supplies many muscles, either directly or through nerves originating from L3. They may be innervated with L3 as single origin, or be innervated partly by L3 and partly by other spinal nerves. The muscles are: quadratus lumborum ...
Radiofrequency targeted vertebral augmentation is a minimally invasive procedure designed to preserve good bone while performing vertebral augmentation (sometimes referred to as kyphoplasty). [2] With traditional kyphoplasty, a balloon is used to create a space within the cancellous bone and then cement is injected into the space.
